Modeling 2015–16 Zika virus epidemic

In mid-May 2015 the Zika Virus (ZIKV) was confirmed responsible for a growing number of cases of an exanthematic disease spreading through a number of Brazilian states. Since that time, transmission of Zika virus has occurred throughout much of the Americas and as of July 14, 2016, a total of 50 countries and territories worldwide reports active transmission of Zika virus (http://www.cdc.gov/zika/geo/active-countries.html). In this project we used a data-driven global stochastic and spatial vector-host epidemic model to provide a quantitative analysis of the spreading pattern of ZIKV in Latin America. We estimated that the first introduction of ZIKV to Brazil likely occurred between August 2013 and April 2014. We provided simulated epidemic profiles of incident ZIKV infections for several countries in the Americas through year 2017. </div>
